Characterization of XylE

Identification of optimun wavelength for measuring absorbance

Spectra of XylE transformed E.coli after addition of catechol assay. The broad peak around 380nm wavelength arises is due to the presence of the product of the enzymatic reaction involving pyrocatechol and XylE enzyme. This peak if absent if a culture of XylE transformed cells are measured without the addition of catechol
